I didn't get it installed but it's pretty well ready to go. I'm still waiting for brake lines. I thought I'd found them at CB Performance but a call to them revealed that their web description is incorrect and the hoses they describe (and that I wanted) are not available.
They referred me to Fast Fab but I haven't heard back from them yet.
Maybe in the West Coast this isn't a big deal...but each one of those washers is another spot for corrosion to start.
If I wind up keeping the brakes long term, I'll get proper brackets made if I get around to restoring the car.
